PURPOSE: A pump using magnetic impeller is provided to prevent noise by applying a uniform acting force to the rotating shaft, while simplifying structure and allowing liquid to be discharged in a convenient manner. CONSTITUTION: A pump comprises a driving unit(1) for discharging a liquid; a cylindrical case(2) having an inlet port(21) and an outlet port(21'), and which accommodates the driving unit and supports the driving unit to rotate; and magnet units(3,3') disposed inside of the cylindrical case so as to rotate the driving unit. The driving unit rotates by the magnetic force of N-pile generated from the magnet units, and discharges a liquid. The cylindrical case includes an impeller(11) constituted by a plurality of rotating blades and disposed inside of the cylindrical case, wherein the rotating blade is formed of a magnetic member. Electro-magnets(32) being driven by an external power are arranged along the outer circumference of central portion of the pump case, wherein electro-magnets are arranged twice of the rotating blades formed of a magnetic member.
